Answer:

y + 1 = 8/9(x +4)

Step-by-step explanation:

Find the slope: [7- (-1)]/ [5 - (-4)] = 8/9

Using (-4, -1)

y-(-1) = 8/9[x- (-4)]

y + 1 = 8/9(x +4)

What is the vertex of y=-3x^2+6x+15? Help is much appreciated.
DENIUS [597]

Answer:

<u>(1, 18)</u>

Step-by-step explanation:

Rewrite the equation in vertex form by completing the square for -3x^2 + 6x + 15. This = -3(x - 1)^2 + 18.

Set y equal to the new right side.

y = -3(x - 1)

Use the vertex form, y = a(x - h)^2 + k, to determine the values of a, h, and k.

a = -3

h = 1

k = 18

Vertex = (h, k) / (1, 18)

Which is a true statement about an isosceles right triangle?
AnnyKZ [126]

Let l be the length of a leg. Using the pythagorean theorem, the hypotenuse is

h = \sqrt{l^2+l^2}=\sqrt{2l^2}=l\sqrt{2}

So, the hypotenuse is \sqrt{2} times as long as either leg.
